Why can't places just serve both? I get so sick of going somewhere that has only Coke or only Pepsi. You either like one or the other so they automatically make some people unsatisfied with their choices. I think it would be a great marketing tool to advertise that we serve both. I say have Coke and Pepsi with their diet equivalents, Mt. Dew, Dr. Pepper, Sprite, and the usual choice of juices.
